Short wave crystal radio

[doesnotcompute81]

@cranelift - how many turns on your coil?

[RascalCoyote]

Oh and that's not short wave, it's medium wave AM broadcast.

[RascalCoyote]

Do you have a schematic ?

[benjwgarner]

How many turns do you have on the coil, and what is the capacitance on the capacitance substitution box?

Gotta love those geranium diodes! Hi! 73 de AA9UC

[Ilovemyoldguitar]

geranium diodes? I think you mean germanium. The geranium diodes are probably better than the daffodil diodes though :)

[Ucster]

But you actually say "geranium" in your video. Still a good video and I enjoyed it, though.

@Ucster Wow never realized I loved flowers so much. oh well, all in fun

Man that looks way harder than what I thought.

I did the same thing using a long piece of wire, a coil wrapped around a film canister, a 40NPO orange capacitor, and a tuning capacitor out of a cheap AM radio. I hooked it to that exact model of speaker and heard a bunch of shortwave religious stations. I call it the Jesus radio.

your comment made me smile XD

[Ucster]

Every crystal set I ever built received the religious stations better than anything else. I'm glad someone else has the same results.

I also built a xtal shortwave radio back in 87,but I use two toilet paper tubes hooked up in parallel. And on one tube I tapped the coil for better selectivity. And a variable cap aross all of that,but the tapped coil gave most of the tunning! I also used the same radioshack audio amp!! Radio mexico and ( at the time) the BBC came in quite strong!!!!!!

can u send me the circuit of this type of radio?thanhks

OMG what is this?????is that a bomb???

[ZealDisarray]

nice
